' Application on April 3.190s. Serial No. 309.622.

vessel is completely under the-control of the operator.

- A further object of the invention is to rovide an air-ship embodyingan aerop ane having a gas bag or receiver secured thereto and providedwith side propellers for elevating and directing the course of thevessel.

A further object is to providemeansfor varying the angle or inclinationof the feathering propeller blades so as to change the i thrust of saidblades and thereby cause the i latter. to pull in any desired direction.

A still further '0 bject 'of the invention is to generally improve thisclass of devices so as to increase their utility, durability andefliciencv.

With these and other objects .in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, and illustrated inthe accompanying drawings it beingunderstood that various changes in form, proportions and minor detailsof construction may be resorted to within the scope of the appendedclaims.

in the accompanying drawings forming a part of this Specification:Figure l is a perspective view of an air-ship or vessel constructed inaccordance wit 1 my invention; Fig. 2 is a side elevation of one of thepropelling blades and a portion of the operating shaft. Fig. 3 is afront elevation of the same. Fig. 4 is a detail perspective view of therotating collar or cam, and-Fig. 5 is a perspective View ol' a portionof the operating shaft and one of the propelling blades illustrating amodified form of the invention.

The improved ship or vessel consists of an aeroplane 5 of an suitablelength and width and to the upper face of which is secured in anysuitable manner a gas bag or receiver 6 to assist in elevating the shipand su porting the same in the air. -Suspended rom the aeroplane 5 andsecured thereto in any suitable manner as by braees-7 is a basket or car8 the latter having its opposite ends inclined or beveled as indicatedat 9 and its intermediate portion reinforced at 10 toform a platformadapted to receive a gas-engine, motor or other source of power 11.opposite sides of the car or basket 8 and secured in any suitable mannerto the platform 10 are uprights or standards 12 novided with terminalbearings 13 in whic 1 is journaled a transversely disposed shaft 14 theopposite ends of which project beyond -the bearings 13 and are providedwith enlarged heads, 15. Extending transversely tln'ouglhthe heads15 andmounted for rotation t erein are stub shafts 16 carrying propellerblades .01 fans 17, the latter being preferably disposed at right anglesto each other as shown. Keyed or otherwise rigidly secured to thetransverse shaft 16 on each side of the head 15 are tappet arms 18adapted to engage a cam face 19 on the collar 20. The collar 20 ismounted for rotation on the shaft 14 and is provided with a plurality ofperipheral pins or. projections 21 by means of which the collar may berotated so as to change the location or position of the cam face 19. Asa means for locking the collar 20 against rotation there is rovided asuitable pin 22 which extends t n'ough a transverse opening 23 in thestandard 12 and projects in the ath of movement of the collar 20 so thatt 1e pins or finger ieces 21 will enga e the projecting end 0 thelocking mem )erv 22 and thus ock the collar against rotation on theoperating shaft. The tap pets 18 are-provided with curved portions 2-1or engagement with the cam 19 and are also formed with reducedextensions 25 adapted to en age suitable stop-pins 26 extendinglaterally from the;head 15. The tappets 18 are so disposed that whenin'engagement with the cam 19 they will turn the blades 17 through auarter of revolution and thereby feather said blades, the stop-pins 26serving to limit the rotary movement of the latter. It will thus beseenthat by rotating the collars 20 the cam 19 may be positioned as tochange the angle or thrust of the fans or blades and thereby cause thelatter to pull up or down or impart a forward or rearward motion to thevessel while by locking one of the collars 20 against rotation on theshaft i strata 14 and partially rotating the opposite collar whichmotion is imparted to said driving.

shaft.

In Fi 5 of the drawings there is illustrated a modi led form of theinvention in which the terminal pins or fin er pieces 21 are dispensedwith and the co lar 20' formed with spaced peripheral teeth or lugs 29adapted to engage a sprocket chain 30, the letter being connector to asprocket wheel disposed within the car and rotated by a suitable crankso that by operatin the crank the collar 20 may be rotated to c ange theposition of the cam 19 without the necessity of manually turning saidcollar. In this form'of the device the fiat surface of thecollar-20 ispierced by a plurality of spaced transverse holes 31 adapted to receivetin. locking pin 22, the construction being otherwise ractically thesame as that shown in Fig. 1 of the drawings.

From the foregoing description it is thought that the construction andoperation of the device Will'be readily understood by those skilled inthe art and further descrip-.

A .tion thereof is deemed unnecessary.

Having thus described the invention What is claimed is:

1. In aerial vessels, the combination with an aeroplane, of a gasreceiver secured to the upper surface thereof, a car suspended from theaeroplane, standards secured to the car, an operating shaft journaled inthe stand ards and extending transversely of the car, featheringpropeller blades carried'by the shaft and mounted for rotation in avertical plane oneach side of the car, camsmounted .for rotation on theo crating shaft and provided with terminal nger pieces, tappets se curedto the blades and adapted to engage the cams for varying'the angles oftheblades, and means engag i "1g the finger pieces for looking the camsagainst rotation.

2. In aerial vessels, an aeroplane, a gas receiver secured thereto, acar suspended from ,the aeroplane, standards secured to the-car,

a shaft journaled in the standard and extending transversely 'of thecar, feathering blades carried by the shaft and mounted for rotation ina vertical plane on each side of the car, collars mounted for rotationon the shaft and provided with cam faces, tappets carried by the bladesand adapted to engage the cam faces for varying the angle of the blades,finger pieces projecting laterally from the collars, and pins extendingtransversely across the standards and engaging the finger pieces forlocking the collar against rotation.

3. In aerial vessels, the combination with an aeroplane, of a gasreceiver secured thereto, a car suspended from the aeroplane, anoperating shaft provided with terminal heads, feathering blades mountedfor rotation in said heads, cams mounted for rota: tion on the operatingshaft, tappets carried by the blades and adapted to engage thecams,.stop-pins secured to the heads for limiting the movement of thetappets, and means for locking the cams against rotation.

4. In aerial vessels, the combination with an aeroplane, of a gasreceiver secured thereto, a car suspended from the aeroplane, anoperating shaft extending transversely of the car and provided withterminal heads, feathering propelling blades mounted for rotation in theheads, collars mounted for rotation on the operating shaft and eachprovided with a cam face, tappets carried by the blades and adapted toengage the cam faces, pins carried by the heads for limiting themovement of the tappets, finger piecesextending laterally from theperiphery of the collars, and

means en a in the fin er ieces for lookin an aeroplane, of a relativelyflat gas receiver secured to the upper surface thereof, a car suspendedfrom the aeroplane and having its opposite ends inclined or beveled,standards secured to the car and provided with terminal bearings, anoperating shaft journaled in said bearings and provided with enlargedheads, feathering blades carried by the heads and mounted for rotationin a horizontal plane on each side of the car, collars mounted forrotation on the operating shaft and each provided with a cam face,tappets secured to the blades and adapted to engage the cams, pinscarried by the heads for limiting the movement of the tappets, fingervpieces extending laterally from the periphery of the collars, lockingpins extending transversely through openings in the standards andadapted to engage the adjacent fingcr pieces for locking the collaragainst rot ation, and means for operating the sha t t.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two Witnesses.
